Uncover the Core Components and Technical Principles of the Double - Head T - Type Welding Machine

In modern manufacturing, the double - head T - type welding machine has become an essential device in various production scenarios due to its high - efficiency and precise welding capabilities. Today, let's take a deep dive into the core components and technical principles of the double - head T - type welding machine to reveal its secrets.

Core Components Unveiled

Pressurization System

It usually adopts either pneumatic vertical pressurization or hydraulic vertical pressurization. This design ensures that the workpieces are firmly clamped during the welding process, resulting in aesthetically pleasing, robust weld joints with minimal slag inclusion. For instance, the pneumatic pressurization system uses high - performance pneumatic components, and its main shaft and guide shafts are made of chrome - plated round bars. This setup enables flexible and reliable pressure transfer and effectively prevents the occurrence of voids, guaranteeing welding stability.

Welding Transformer

Most welding transformers are cast with epoxy resin and have their secondary sides internally cooled by forced water circulation. Made of high - permeability magnetic materials, they feature low no - load losses, strong and stable power output, and a long service life. A stable power output is crucial for ensuring welding quality as it can provide appropriate welding energy under different working conditions.

Controller

Generally, it adopts a single - chip microcomputer integrated control system and can be equipped with high - precision digital buttons or touch - type switches. Through this controller, operators can input parameters such as pre - pressure, wave head, welding time, holding pressure, rest time, and welding current. Some controllers also have functions like dual - foot pedal operation, dual - pulse control, dual - current control, and SCR temperature rise monitoring, which greatly enhance the operational convenience of the equipment and the controllability of the welding process.

Electrode Part

The copper chuck often has a semi - circular or flat - shaped design, which makes it convenient to install tooling fixtures to meet the welding requirements of workpieces with different shapes and sizes. Since the electrode is in direct contact with the workpiece during the welding process, its performance and design directly impact the welding quality.

In - Depth Analysis of Technical Principles

The double - head T - type welding machine mainly operates based on the resistance welding principle. During welding, first, the welding parts of the two workpieces are closely fitted together. Then, an electric current is applied to the workpieces through the electrodes. Due to the resistance at the contact parts of the workpieces, when the current passes through, resistance heat is generated, rapidly heating the contact parts to a plastic state. As the heat accumulates, the welding area gradually reaches the melting state, forming a weld spot. Throughout this process, the pressurization system continuously applies pressure to ensure that the workpieces remain in close contact, promoting the fusion of metals. After welding is completed, a upsetting pressure is quickly applied (or the welding pressure is maintained) to make the welded parts more secure, ultimately completing the entire welding process.

Operation Suggestions

Parameter Setting

Before starting welding, be sure to carefully adjust the welding parameters such as welding current, time, and pressure according to the material, thickness, and welding requirements of the workpiece. When using the machine for the first time, you can conduct small - scale parameter tests first. Find the most suitable parameter combination and then start large - scale production.

Workpiece Preparation

Ensure that the welding surface of the workpiece is flat and clean, free of oil, rust, and other impurities. These impurities can affect the conduction of the welding current and the generation of heat, leading to a decline in welding quality.

Equipment Maintenance

Regularly inspect all components of the equipment, especially the electrodes, pressurization system, and cooling system. Clean the oxides on the electrode surface in a timely manner to ensure good electrical conductivity. Check the sealing and pressure stability of the pressurization system. Ensure the normal operation of the cooling system to prevent the welding transformer and other components from being damaged due to overheating.

The double - head T - type welding machine plays a vital role in the metal welding field with its unique core component design and advanced technical principles.
